Abstract

The invention relates to the field of rail vehicle bogies, and provides a single-pull-rod traction pin boss for a bogie, the bogie and a rail vehicle. The single-pull-rod traction pin boss for the bogie comprises a vehicle body sleeper beam connecting seat, a pair of transverse stop baffles, a traction pull rod mounting seat and a pair of vertical stop mounting seats, wherein the pair of transverse stop baffles are oppositely arranged on the two transverse sides of the vehicle body sleeper beam connecting seat, and a transverse shock absorber mounting seat is formed at the bottom of one transverse stop baffle; the traction pull rod mounting seat comprises a pair of traction pull rod mounting supports which extend downwards along one longitudinal side of the vehicle body sleeper beam connecting seat and are arranged side by side at intervals, the pair of traction pull rod mounting supports are located between the pair of transverse stop baffles, and through holes are formed in the pairof traction pull rod mounting supports; and the pair of vertical stop mounting seats are formed at the bottom of the traction pull rod mounting supports, and a mounting hole is formed in each verticalstop mounting seat. The technical problem that an existing single-pull-rod traction device is difficult to install in a bogie due to the fact that the occupied space is large can be solved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies, in particular to a single tie rod traction pin seat for a bogie, a bogie and a rail vehicle. Background technique [0002] There are many kinds of central traction devices currently applied to rail vehicle bogies, which are generally divided into Z-shaped double-rod traction devices and single-rod traction devices. The Z-shaped double-tie rod traction device includes a traction pin seat and a draw beam. One end of the double draw rod is connected to the draw beam, and the other end is connected to the frame. This kind of traction device has a relatively complicated structure and requires a large space. In the single-tie-rod traction device, the traction beam is generally canceled, and one end of the traction rod is directly connected to the traction pin seat, and the other end is connected to the frame. The current single tie rod traction device is generally installed in a low-positi...
